  • Joules are a measurement of energy. "Joule Thief" is a misleading name as energy has to **ALL** come from the battery. You obviously have created a self-excited oscilator with a voltage multiplier voltage step-up circuit..

    Giving the schematic for your cute circuit would be much more honest than trying to impy "light from nothing"

  • @JoeFitant

    I know what a Joule is. I did not name the circuit. I think it is called a "Joule Thief" because it steals every last joule from the battery that is powering it. I never tried to imply that the light came from nothing. I cannot believe that you thought i was implying that the "light came from nothing". Why do you think I show the battery and the solar panel? The energy obviously comes from the solar panel. Where did you get the quote "light came from nothing".?

  • I have followed your Air Battery Experiments and I think you are inspirational! This Solar cell - Joule Thief Setup is amazing!!! If you can run leads down inside of a fallout shelter, this would make for some pretty awesome for emergency lighting.

    Thanks for your time and creativity!

see all

    Quit trying to sound intelligent on the internet. Its pathetic and you're not succeeding at all at it.

  • you can get led bulbs that cheap in America? the cheapest ones here are 20-40 usd each, which is a stupidly high price

  • brilliant videos and work you have done here... do you have a schematic for wiring the solar charger to the joule thief?.... cheers. keep up the great work.

  • is the light bright enough to power the solar panel? if so, the light could keep itselft going.....then disconect the battery, maybe

  • @lightsaber - I didn't get it from the video, but I wonder if the solar panel is big enough to both charge the batteries -and- run the lights?

    Nice demo. This would make for a very cheap and bright bike light. ;-)

  • @JoeFitant - If you know what "Joule Thief" means, then you wouldn't criticize someone for using the term. It does not matter if the term is "accurate" to the depth you interpret it to mean, joule thief is a de facto term.

    I checked your profile, and it looks like you are real busy here at YouTube, criticizing everybody. You actually use Search to find people to offend. Congratulations, you are the first person I have ever blocked.

  • @XRayCam You are absolutely right about that,but my wonder is a positive thing in my case lol

  • What I really want to know is how long will the lights run off the single batter?

  • @HiFiman4u, I am sure you wonder of your own brain at times too ;-)
